Abstract: 1,240,177. Testing vehicle torque electrically. SUN ELECTRIC CORP. Nov. 14, 1968 [Nov. 14, 1967], No.54065/68. Heading G1N. Apparatus for measuring the torque exerted by the wheels of a vehicle comprises a roller stand for locating the driving wheels of the vehicle, each roller having a tachogenerator, and an eddy current brake whose force is measured by the twist of a spring-loaded stator, whereby the pull required to maintain a desired speed or acceleration is determined. The frequency speed signals from four independent photo-electric tachogenerators 14a-d Fig. 1 associated with the left and right hand rollers 1-4, are converted to corresponding voltage amplitudes and combined to feed a speedometer. Rollers 1, 3 are each coupled to an eddy current brake 9 comprising a D. C. -energized stator and two rotors, one fixed to a shaft 7 of roller 1 and the other fixed to shaft 8 of roller 3. Rotation of the rollers drags the stator of brake 9 against a spring 11 through an angle proportional to the torque exerted by the brake and measured by rotary potentiometers 12, 13. The speed signal is differentiated to provide an accelerating force signal, which is added to the brake torque signal to determine the total pull exerted by the wheels. If the speed is maintained constant, the braking torque is equal to the pull of the wheels. To determine the effect of different road conditions, the stator of the eddy current brake 9 is energized, as shown in Fig. 5, by the sum of voltages comprising; (a) a voltage U'p representing the torque of the brake, obtained from rotary potentiometer 13 coupled to the stator of the brake. (b) a voltage Ulw representing air resistance, obtained by squaring the speed signal Uvt and multiplying by factors representing the air resistance of the vehicle and the air density. (c) a voltage Uh representing the effect of ascending a slope, obtained by appropriate adjustment of the slider of a potentiometer 43 fed with a constant voltage 42. (d) a voltage Uak representing the additional force required for acceleration, obtained by differentiating the speed signal at 44, and multiplying it at 45 by a factor depending on the weight of the vehicle. The system may include a timing arrangement Fig. 6, (not shown) for measuring the time taken to change from one speed to another.
